Bill Kriskovich Head Coach
I started swimming when I was 10 and began coaching summer league when I turned 19 in the East Bay Swim League with the Drowning Darryl's swim team. I have such great memories both swimming for and coaching the Darryl's and look forward to making more memories here with RMST.
I graduated college with degrees in Political Science and Economics and after working towards a credential in teaching I began working as a PE teacher in Fremont for 25 years. I love basketball. I play golf and enjoy traveling, but mostly now I am excited to be back coaching swimming.
I am thrilled to be part of the Seals team and hope to work with everyone to make it a great summer experience.

Simone Ostler Assistant Coach

Hi Seals! My name is Simone Ostler and I just finished up my freshman year at Texas Christian University where I am studying early childhood education. I am super excited to be returning as an assistant coach this season! In addition to being an assistant coach, I will be running the seal pup program for a second year. I swam on RMST for six years and then spent the next five years swimming year round for Orinda Aquatics. This will be my sixth season coaching for RMST. My passions are swimming and teaching and I love sharing that with our swimmers. I can't wait to have another amazing season with y’all, GO SEALS!!

Jack Gullum Junior Coach

Hey Everyone! My name is Jack Gullum and I'm currently a Sophomore at De La Salle High School. I have been on the Seals for 10 years since I was a seal pup, and this will be my second season as a junior coach. My favorite swim events are free and breast, and I enjoy riding my long board around the neighborhood. I look forward to coaching this season and I can't wait to meet you all, GO SEALS!!!
